    I absolutely hate that this is black

    ...and yet this is a five star review. I like this product so much that I came back for a second round replacement after my first hit its life span, in spite of that design flaw. I've used a bunch of cups and this is the easiest to use while still being completely comfortable. My problem with the black color is that it makes it SO hard to clean effectively, you just can't see if it's all the way clean very well, let alone check on the status of things during removal to track where your cycle is. I have to turn on my brightest light and still squint to make sure I get it clean. All the lighter colored ones I've used simply do not have this issue. So I hope that if someone at Flow sees this review, they take it as the huge compliment I mean it as, but also maybe consider an untinted or pale colored alt color release.

    Best cup option. Best menstruation product period.

    I will never turn back after using FlexCup. I tried 6 other cups before finding FlexCup size 2 & it's been 7 years of less stress, mess, & pain. It has made my life so much better, truly.

    I got a tubal ligation 7 years ago after 4 sons. Prior to the procedure, I had light, 3 day long cycles, but after, I was in hell... 8-14 day cycles that had me bleeding through tampons & pads every hour. Let's not even mention the cramps. I'd rather have another kid, my goodness. I was hopeless & scared, but FlexCup saved the day & many days after that.

    EVERYONE SHOULD HAVE ONE

    i would always use tampons. never pads, they gave me rashes. but after a while of being completely annoyed by the process, $ (of both buying them and toilet paper to wrap them in to dispose of), and just the general health issues - this was crazy. i called my sister and told her she had to buy one, i think cups should be way more popular than they are!!! especially this one, my boyfriend bought me the wrong size (2 instead of 1) at walmart, and they reimbursed me with a size 1 free of charge! absolutely amazing company. i love flex so much !!!!!! ugh!!!!!

    Flex cup size 1 and 2

    First of all I really need to say i have used tampons for over 20 years! A few years back I used the flex disposable disc's and they were great, however after having my 3rd baby my pelvic floor changed and it became difficult to use personally. But I bought both size cups this last month and girl, let me tell you I love it! Not 1 leak! It definitely was easy to use and clean and I'm 95% sure it relieved alot of my cramps this month! Its a wonderful product I 100% recommend! Let's be honest too were saving money ladies, finally a product that is safe and cost effective and comfortable 👍 😉 we're winning! I have made a couple recommendations of two new products to the company hopefully we will see them soon! Also flex im your biggest supporter 💪 I'd be interested in samples haha
